Note—A Note on Including Ordinal Relations Among Multipliers in Data Envelopment Analysis
扩展了数据包络分析（DEA），使其能处理某些维度权重之间存在序关系的情况，并通过累加部分输入输出因子将扩展模型简化为原始DEA形式，附有示例和应用方向。
Data Envelopment Analysis (DEA) evaluates the efficiency of Decision Making Units without imposing a priori weights on the input and output dimensions involved. This Note extends DEA to situations where ordinal relations among weights corresponding to certain dimensions exist. The extended model is reduced to the original DEA formulation where some of the input and output factors are accumulated. An illustrative example is provided and potential areas of applications are pointed out.
